ENEE 302 Possible to do items.
1. For the following circuit calculate analytically the pulse response vout(t) to the pulse
vin(t) = A*[1(t) - 1(t-T)], where 1(t) is the unit step response.
(2.1)
Do this for arbitrary A both positive and negative and for two values of T, one and
five time constants.
Assume that the capacitor is initially uncharged at t=0. Check this by running Spice.
2. Assuming that the diode connected transistor in the following is ideal, sketch vout(t)
for the pulse of (2.1) above. Using C=1uFd and A=2v, T=10us run Spice to check
your sketch and explain differences.
3. Repeat 2. on the following two circuits.
